Lets start with this:
Options > Address Book > Add New > IT SAVES AND DISPLAYS THE HOLE PATH AS FOLLOWS - I have had this issue from your first release but never bothered with it until now!

C:\Program Files\PocoMail3\Address\MailingList it does not display like the normal book "Address" so when I run Send To All Script new or old version I get the following error which I believe is caused by the way the > Add New:

Here is the error when I try to use the Send All script:

An error has occured in Send To All $ErrorResult.File not found: "C:\PROGRA~1\POCOMA~1\Address\C:\Program Files\PocoMail3\Address\MailingList.ini

$ErrorLine: OpenBody $address $path

If I run the normal Address > it works fine.

I have unstalled PocoMail3, went through the register file and removed all Poco files, and re-installed it, and I still get the above error message

I'm not sure why the names of the address books contains the full path when you create a new one. I tried it here and its okay unless i create the address book in a different folder to the default. To fix this, the code below checks for a colon in the address book name and assumes the name contains the full path if the colon is present, otherwise it appends the name to the address book folder as it did before:
